When the screen of a Xiaomi smartphone stops responding to touch or goes out completely, it always takes you by surprise, at which point the device continues to work, consuming battery power and heating, and you can't complete processes or restart the system, and this is especially critical when the phone needs to be turned off for transportation to the service or to save the battery.
Compounding the problem, modern MIUI and HyperOS interfaces are sharpened to control the finger, and physical buttons often only serve as locking, but there are proven methods to force the system to shut down even when the display is completely out of order.
In this guide, we’ll look at all the options you can get from simple button combinations to cloud services and computer utilities, how to safely shut down a device without damaging the file system, and what nuances you need to consider for owners of different models.
Hardware reset via button combination
The fastest and most affordable way to turn off a smartphone with a broken touchscreen is to use physical control buttons. In most Xiaomi, Redmi and Poco models, pressing the power button for 10-15 seconds causes a forced reboot or a complete shutdown, bypassing the software menu.
If a standard long press doesn't work, try Volume Down + Power. Hold both buttons at the same time for 20 seconds. This method emulates battery extraction and often helps when the system is stuck. It's important not to let go of the buttons until a vibration or logo appears.
⚠️ Warning: Forced shutdowns can result in loss of unsaved data in open applications. Use this method only if the screen is not fully responsive.
Some older models have a Volume Up + Power scheme, so if neither of these works the first time, repeat the procedure, but increase the retention time to 30 seconds, and sometimes the system takes longer to process the interrupt.
💡
If the phone vibrates but the screen remains black, try pressing the volume button quickly several times in a row - this can "wake up" the backlight for a couple of seconds, allowing you to see the menu.
Use of Mi Cloud and Find Device
If your smartphone is connected to the Internet and the Device Search feature has been activated in advance, you can control power remotely, one of the most secure software methods that doesn't require physical contact with a damaged display.
Go to the official MI Cloud website from any other device (computer or tablet) and log in under your Mi Account. In the management menu, select the option “Clear Data” or “Block”, which in some versions of the firmware initiates a reboot or turn off the device for security.
- 📱 Open your browser and go to i.mi.com.
- 🔐 Enter the username and password from the Mi Account installed on the problem phone.
- 📍 Select your device from the list at the top of the screen.
- 🔌 Click the “Switch Off” or “Clear” button (depending on the interface version).
It is worth noting that remote shutdown functionality is directly dependent on the MIUI version and security settings. In newer versions of HyperOS, this feature may be limited for the purpose of protection against theft, so this method is not 100% guaranteed.
Control over computer and ADB (Android Debug Bridge)
For advanced users who previously had USB debugging enabled, the ideal solution would be to use the ADB utility. This tool allows you to send system commands directly to the Android shell, ignoring the non-working touch layer.
First, you need to install the Xiaomi USB Driver and SDK Platform Tools on your computer. Connect your smartphone with a cable to your PC. If the Allow Debugging window appears on the screen before, and you tick the Always Allow box, the connection will be automatically established.
adb shell reboot -pThe input command adb shell reboot -p sends a signal to completely turn off the power. the alternative command adb reboot will perform the restart. If the command does not execute, check the connection status through adb devices.
What if the ADB can’t see the device?
Use of USB-OTG and computer mouse
If the touchscreen is broken, but the image on the matrix is present, the USB-OTG adapter will help save the situation. Connecting a regular computer mouse through an adapter, you will get a cursor on the smartphone screen, which can be controlled without touching.
This method allows you not only to turn off your phone, but also to save important data, back up or turn off alarms. Just plug in your mouse, wait for the cursor to appear, and click the off button in the interface in the standard way.
☑️ Preparation for connecting the mouse
It is important to note that not all Xiaomi models support OTG operation in a switched-off state or in critical system errors, but in 90% of cases, the cursor appears immediately after connecting the peripherals.
Comparison of disconnection methods for different breakdowns
The way you turn off depends on the nature of the malfunction, and if only the glass is broken and the image is there, one approach, but if the matrix is black and only vibration works, a completely different approach.
Below is a table that helps determine the best course of action depending on the symptoms of your device malfunctioning.
| Symptom of breakdown | Does the image work? | Does the touchscreen react? | Recommended method |
|---|---|---|---|
| Broken glass | Yes. | Partially/No | USB-OTG + Mouse |
| Black screen (system alive) | No. | No. | Long push of the buttons |
| Full zavison (freeze) | Yes/No | No. | Combination Loudness + Nutrition |
| USB debugging enabled | Whatever. | Whatever. | ADB teams with PC |
Note that if the phone is heated, it is recommended to remove the case and put the device on a cold surface before any manipulation, which will reduce the risk of battery damage during forced on-off cycles.
Specificity of Redmi and Poco models
Redmi and Poco sub-brands often have their own button layouts and response to commands, for example, in the Poco F series, the power button can be combined with a fingerprint scanner, which changes the way you press.
In some cases, on smartphones with a side scanner, double or triple pressing the lock button helps, and it is also worth trying to press the volume button, since in some firmware this causes an emergency call menu, from where you can sometimes go to power management.
💡
For models with a side fingerprint scanner, prolonged retention of the lock button (15+ seconds) is the main way to emergency shutdown.
If you have a model with an IR port, theoretically you can try to control the phone through the remote, but you can not turn off the phone with standard Mi Remote means, since the IR port works only when the system is active and allows external commands, which is difficult to do with a broken screen.
Prevention and preparation for the future
To avoid a black box problem at a critical moment, you should prepare the device in advance. Enabling debugging over USB and setting the unlock password (which you remember) greatly expand the recovery options.
Check your Mi Cloud cloud sync regularly, and if your contacts, photos, and notes are saved automatically, a screen break will be a temporary inconvenience, not a data loss disaster.
- 🛡️ Always keep your Mi Account password in a safe place.
- 🔋 Keep your battery in check so your phone doesn’t run out at the wrong time.
- 🔌 Have an adapter on hand USB-OTG, It is inexpensive and takes up little space.
Remember, self-opening the case to disable the battery plume when the screen is broken is a last resort. It can disrupt the water protection and lead to loss of warranty. Use software and hardware buttons first.
